      Vaverka, Jakub; Pellinen-Wannberg, Asta; Kero, Johan; Mann, Ingrid; De Spiegeleer, Alexandre; Hamrin, Maria; Norberg, Carol; Pitkaenen, Timo (Journal article; Peer reviewed, 2017-06-29)
      We present the first study of dust impact events on one of the Earth‐orbiting Cluster satellites. The events were identified in the measurements of the wide band data (WBD) instrument on board the satellite operating in monopole configuration. Since 2009 the instrument is operating in this configuration due to the loss of three electric probes and is therefore measuring the potential between the ...

The aim of this tutorial review is to give insight into the practical use of the PE model. Starting from a set of molecular structures and until you arrive at the final property, there are many crucial details to ...
    • Can a large-mesh sieve panel replace or supplement the Nordmøre grid for bycatch mitigation in the northeast Atlantic deep-water shrimp fishery? 

      Jacques, Nadine; Herrmann, Bent; Larsen, Roger B.; Sistiaga, Manu Berrondo; Brčić, Jure; Gökçe, Gökhan; Brinkhof, Jesse (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-26)
      The Nordmøre grid is the principle bycatch mitigation device in many shrimp trawl fisheries. However, in several of these fisheries, bycatch is a problem because small sized fish can pass through the grid and enter the codend together with the targeted shrimp. One such fishery is the Northeast Atlantic deep-water shrimp (<i>Pandalus borealis</i>) fishery, where the use of a Nordmøre grid is mandatory. ...
    • Evidence of Isotopic Fractionation During Vapor Exchange Between the Atmosphere and the Snow Surface in Greenland 

      Madsen, M.V.; Steen‐Larsen, H.C.; Hörhold, M.; Box, J.; Berben, Sarah Miche Patricia; Capron, E.; Faber, Anne-Katrine; Hubbard, Alun Lloyd; Jensen, Mari Fjalstad; Jones, T.R.; Kipfstuhl, S.; Koldtoft, I.; Pillar, H.R.; Vaughn, B.H.; Vladimirova, D.; Dahl‐Jensen, D. (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-02-18)
      Several recent studies from both Greenland and Antarctica have reported significant changes in the water isotopic composition of near‐surface snow between precipitation events. These changes have been linked to isotopic exchange with atmospheric water vapor and sublimation‐induced fractionation, but the processes are poorly constrained by observations. Understanding and quantifying these processes ...

      We present a flexible and efficient framework for multiscale modeling in computational chemistry (MiMiC). It is based on a multiple-program multiple-data (MPMD) model with loosely coupled programs. Fast data exchange between programs is achieved through the use of MPI intercommunicators. This allows exploiting the existing parallelization strategies used by the coupled programs while maintaining a ...
    • Modeling distracted performance 

      Hawkins, Guy E.; Mittner, Matthias; Forstmann, Birte U.; Heathcote, Andrew (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-05-23)
      The sustained attention to response task (SART) has been the primary method of studying the phenomenon of mind wandering. We develop and experimentally test the first integrated cognitive process model that quantitatively explains all stationary features of behavioral performance in the SART. The model assumes that performance is generated by a competitive race between a stimulus-related decision ...
    • Exploring the overlapping binding sites of ifenprodil and EVT‐101 in GluN2B‐containing NMDA receptors using novel chicken embryo forebrain cultures and molecular modeling 

      Fjelldal, Marthe Fredheim; Freyd, Thibaud; Evenseth, Linn; Sylte, Ingebrigt; Ring, Avi; Paulsen, Ragnhild Elisabeth (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-05-30)
      N‐methyl‐d‐aspartate receptors (NMDAR) are widely expressed in the brain. GluN2B subunit‐containing NMDARs has recently attracted significant attention as potential pharmacological targets, with emphasis on the functional properties of allosteric antagonists. We used primary cultures from chicken embryo forebrain (E10), expressing native GluN2B‐containing NMDA receptors as a novel model system. ...
    • MicroRNA 141 is associated to outcome and aggressive tumor characteristics in prostate cancer 

      Richardsen, Elin; Andersen, Sigve; Melbø-Jørgensen, Christian; Rakaee, Mehrdad; Ness, Nora; Al-Saad, Samer; Nordby, Yngve; Pedersen, Mona Irene; Dønnem, Tom; Bremnes, Roy M.; Rasmussen Busund, Lill-Tove (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-01-23)
      A large number of miRNAs influence key cellular processes involved in prostate tumorigenesis. Previous studies have demonstrated high expression of miRNAs in human prostate cancer (PC) tissues and cell lines. In previous microarray data, we found miR-141 to be upregulated and miR-145 to be downregulated in PC. In this large PC cohort (n = 535), we explored the prognostic role of miR-141 and miR-145 ...
    • Crystallized but not soluble uric acid elicits pro-inflammatory response in short-term whole blood cultures from healthy men 

      Brovold, Henrik; Lund, Trine; Svistounov, Dmitri; Solbu, Marit Dahl; Jenssen, Trond Geir; Ytrehus, Kirsti; Zykova, Svetlana (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-19)
      Several epidemiological studies have pointed at serum uric acid (SUA) as an independent risk factor for mortality, diabetes, hypertension, cardiovascular and kidney disease; however, no clear pathogenic pathway is established. Uric acid (UA) crystals show pro-inflammatory properties and can thus create or contribute to the state of chronic low-grade inflammation, a widely accepted pathogenic mechanism ...

      <i>Introduction</i>: Although the Aberrant Behavior Checklist (ABC) is one of the most widely used behavioral rating scales among people with developmental disabilities, very few studies have examined the factor structure of the non-English versions. <p> <p><i>Methods</i>: The construct validity of the Norwegian ABC was examined in a clinical sample of children and adolescents with neurological ...
    • Distribution and quantification of gas hydrates and free gas in marine sediments of Vestnesa Ridge, offshore W-Svalbard 

      Singhroha, Sunny (Doctoral thesis; Doktorgradsavhandling, 2019-06-18)
      Gas hydrates store a large amount of methane (>500 Gt of Carbon) in continental margins and permafrost environments. Some of these deposits occur in climate sensitive areas, such as Arctic and permafrost settings. Gas hydrates occur extensively in the Vestnesa Ridge, a contourite drift deposit on the western Svalbard margin. The eastern segment of the Vestnesa Ridge is characterized by the presence ...
